Carlton is 6'10 and that's why he plays. It sounds obvious, but it's true. The fact that he has a fairly wide frame and soft hands doesn't hurt. His basketball IQ is there even if his skill set is not. I think he was coached pretty well at Demaha Catholic and I can see why his sturdiness may have appealed to Ollie after coaching Brimah all those years.
Everything else about his game is utterly unremarkable (which puts him in the same category as almost everyone else playing college ball).
Classic high floor, low ceiling player that typically ends up at an upper mid-major or lower p5 school.
